Kicking a ball: The kicking action runs the knee/hip servos at full speed, instead of slow smoothly interpolated sweeps like used in walking/ leaning E.g. CODE: SELECT ALL Servo.hip = 90 Servo.hip= 140 vs CODE: SELECT ALL For sweep in range (90, 140): Servo.hip = sweep time.sleep (0.1) Here’s a quick vid of it falling […]

Bot balancing without gyros … for a few seconds at least No gyros, no accelerometers – only a sonar ranger and lots of code. The motors used are standard servos modified for continuous rotation, sonar sensor is a HC-SR04 as detailed in a previous post Code ? Well here’s a simplified portion of the PID […]
